What marine animals might I see while swimming around Mallorca?

Swimming off the coast here often means choosing between sheltered coves or more open waters, each offering different glimpses of marine life. In places like Cala Mondragó and Cala Llombards, the crystal-clear waters reveal colorful shoals of fish, such as Mediterranean damselfish and wrasse, darting among rocky underwater formations. These protected bays also sometimes welcome the gentle presence of sea bream and the odd moray eel slipping into crevices.

If you venture near the Posidonia meadows around Es Trenc or off Formentor, there’s a good chance of encountering loggerhead sea turtles, which feed on the abundant seagrass. Dolphins are an occasional sight too, especially when swimming further offshore on the north coast, their playful arcs breaking the surface near boat routes. Starfish and sea urchins cling to underwater rocks, adding splashes of color to the seascape, while schools of amberjack and gilt-head bream cruise the depths.

Deeper waters may reveal rays gliding gracefully over sand patches, and while whales pass through more rarely, migrating fin and sperm whales have been spotted around the island’s northern waters during seasonal movements. It’s best to observe all wildlife with respect, avoiding disturbance as these creatures thrive best undisturbed. Between the Tramuntana cliffs and the southern sandy stretches, the island’s marine life complements its stunning landscapes in unforgettable ways.
